EYEGLASS CLEANER.

Application filed February 11, 1927, Serial No. 167,415. Renewed February 6, 1929.

My invention has for its main object the provision of a device for quickly, conveniently, and effectively cleaning eyeazlasza s of the usual type, the device being preferably such that it is conveniently carried in a persons clothes pocket and that it can be held and operated with one hand of the operator, the other hand of the operator being free for holding the eyeglasses during the cleaning operation.

Another object resides in the provision of an advantz'lgeous structure whereby the cleaning; element of the cleaner may be easily and quickly mounted on and dismounted from the cleaner with a view toward facilitating renewal of the cleaning: element.

llith these objects in view my invention consists in certain features of novelty in the construction, con]bination and arrange ment of parts by which the said objects and certain other objects hereinafter appearing, are effected, all as fully described with reference to the accompanying drawing and more particularly pointed out in the ap pended claims.

111 said drawing Figure 1 is a top plan view of an eyeglass cleaner embodying my invention;

Figure 2 is a side elevation of the same;

.lfigure 3 is a view similar to Figure 1 with certain parts removed;

l ig'ure -i is a section of the cleaner on the line i--i of Figure 3;

Figure is a top plan view of the supporting; d ,czlr, hereinafter described;

Figure (l an enlarged partial section on the line of liigure Figure 7 is a side elevation of the cleaning eleniient and attached mounting disk with the peripheral portion of the cleaning element flexed away from the mounting disk to show the peripheral portion of the mounting disk free of the cleaning element as hereinafter described.

Lilac characters of reference indicate like parts in the several views.

Referring to the drawings 1 designates a hollow casing or frame which is of shallow circular formation. Secured on the bottom of the casing and extending upwardly within the casing in coaxial relation therewith is a stud 2, and rotatably mounted on this stud within the casing a hub '3 having a relatively small spur pinion 4 formed thereon. See Figures 3 and 4;. Secured at the upper end of the hub 3 in coaxial relation therewith and with the casing is a support disk 5 which has a diameter slightly less than the internal diameter of the casing. This disk is disposed at the opening of the casing and forms a closure for the same.

Another stud 6 is secured on the bottom of the casing 1 adjacent the periphery thereof and extends upwardly within the casing in parallelism with the stud 2. A lever 7 is pivotally mounted at an intermediate point thereon on the stud 6 Within the casing by means of a hub 8, and the inner end of this lever is formed with an interial spur gear segment 9 which meshes with the pinion l whereby when the lever is oscillated the pinion 4- and with it the support disk 5 is rotated in alternate directions, the gear segment 9 and the pinion 4; constituting multiplying gearing.

A coiled tension spring 11 within the easing has its respective ends secured to the bottom of the casing and to the lever 7 whereby to move the lever 7 in one direction of its pivotal i'noveinent. The lever 7 projects exteriorly of the casing through an opening 12 in the peripheral wall of the casing and a linger hold 3 is formed on this exterior portion of the lever for the manual operation thereof. A second linger hold 14 is formed on the casing exteriorly thereof whereby the cleaner may be held in one hand and the lever 7 be inter-mittently operated against the influence of the spring for rotation of the support disk 5 in alternate directions in an obvious nuniner. The end of the stroke of the lever 7 to which the spring ll operates the lever is shown in full lines and the end of the stroke of the lever to which the operator operates the lever against the inth'lence of the spring is shown in dotted lines in Fig ure 3.

A. cleaning element 15 of suitable cleaning; niiaterial such as cloth is made in the form of a disk approximating the size of the support disk 5 and is thickened at its center portion for the cleaning of the concave surfaces usual in eyeglasses. A. mounting do 16 also approxiun, the size of the su 'iport disk secured at its centen as indicated at 17 in Fl ure 7, in a suitable manner as by glue to the underside of the cleaning element 1.5 in coaxial relation therewith, thus leaving): the peripheral portion of the supporting disk free of the cleaning element. The mountin disk lltl 16 is made of a stiff material such as cardboard which may be flexed slightly, and the support disk 5 is provided with peripheral lugs 18 spaced about the axis thereof, see Figures 4;, '5, and 6, which are adapted for engagement about the periphery of the mountdisk and between peripheral portions of tne mounting disk and the cleaning element 15 and independently of the cleaning element for detachably securing the cleaning element on the supporting disk. Thus, the attaching means, by reason of the engagement of the lugs 18 with the peripheral portion of the mounting disk 16 independently of the cleaning element 15, does not interfere with the use of theentire outer surface of the cleaning element for cleaning, and when the cleaning element is worn or dirty it may be easily and quickly replaced by a new cleaning element.

In cleaning eyeglasses the operator holds the cleaner, by means of two fingers of one hand being engaged in the finger holds 13 an d 14, and intermittently Operates the lever 7 ainst the influence oi the spring 11 for ro ta'ting the cleaning element 15 in alternate directions while applying the surfaces of the eyeglasses held in the other hand of the operator to the cleaning element.

It is to be observed that the mechanism is effectively enclosed and that the cleaner may be made of a size that may be conveniently carried in the pocket of the user.

\Vhile I haveherein shown and particular- 1y described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention, but hav ing thus described my invention, I claim as new and desire to secure by Letters Patent the following 1. Ina cleaner of the character described the COHllJlRItttIOII with a rcvoluble supporting disk, of a cleaning element disk, :1 stilt mounting disk secured at its center to said cleaning clement disk in coaxial relation therewith, and means on said supporting disk and engageable with the peripheral portion ot said mounting disk independently of said clcanin element disk for detachably securing sai cleaning element disk on said sup poi tin disk.

2. In a cleaner of the character described the combination with a revohsble supporting disk, of a cleaning element disk, :1 stitl mounting disk capable of ficxuro and secured at its center to said cleaning clclncnt disk in coaxial relation therewith. and a plurality ol lugs on said sup 'iortingr disk and spacial about the axis thereof and adapted for engagement about the periphery oil said mounting disk and between the mounting disk and said cleaning clement disk for detachably sccuring said cleaning element disk on said supporting disk.

3. In an eyeglass cleaner the combination with a hollow casing of shallow circular formation, of a supporting disk disposed at the opening of the casing in coaxial relation therewith and carried by the casing for axial rotation with respect thereto, a cleaning clcn'ient disk, a relatively still mounting disk capable ot' {tenure and secured at its ('i-lltcl to said cleaning element disk in coaxial relation therewith, and a plurality of peripheral lugs formed on said supporting disk and spaced about the axis thereof and ad aptcd 'l'or engagement about the periphery of said mounting disk and between the mount inn d isk and said cleaning element disk for detachably securing said cleaning element disk on said supporting disk.

In witness whereof I hereunhi atlix my signature this fifth dav of February. 1927.
